If you’re planning a trip to Thailand, there’s some good news that will make your arrival process smoother than ever. Starting May 1, 2025, Thailand is rolling out the Thailand Digital Arrival Card (TDAC)—a streamlined, paperless replacement for the traditional TM6 immigration form. This means faster processing, less paperwork, and an overall better experience at immigration checkpoints. Here’s everything you need to know about the TDAC and how it will impact your journey.
What Is the Thailand Digital Arrival Card (TDAC)?
The TDAC is an online system designed to simplify the entry process for foreign travelers arriving in Thailand by air, land, or sea. By digitizing immigration procedures, it aims to reduce wait times at the airport and improve overall efficiency.
Key Benefits:
- Faster immigration clearance
- No need to fill out paper forms
- Ability to update details before arrival
- Enhanced security and accuracy of travel information
- Better tracking for public health and safety
- Environmentally friendly approach
When and How to Submit Your TDAC
For a smooth arrival, it’s recommended that travelers submit their TDAC application at least three days before entering Thailand. This allows authorities to process and verify your details ahead of time, minimizing delays.
Application Process:
- Visit the official TDAC website at: tdac.immigration.go.th
- Choose submission type – You can apply individually or submit a group application
- Fill out the form – Enter personal details, trip and accommodation information, and a health declaration
- Submit your application – Ensure all details are accurate before confirming
- Save or print your confirmation – You’ll need it for reference upon arrival

Information Required for the TDAC
To complete your TDAC application, make sure you have the following details ready:
1. Passport & Personal Information
- Full name (as it appears on your passport)
- Passport number
- Nationality/Citizenship
- Date of birth
- Gender
- Occupation
- Country & city/state of residence
- Contact number

2. Travel Information

Health & Vaccination Requirements
Travelers arriving from or transiting through Yellow Fever-infected countries must present an International Health Certificate proving vaccination. This is an important requirement to avoid issues at immigration.
Limitations & Things to Keep in Mind
While the TDAC offers many advantages, there are a few important points to note:
- Certain details (passport number, full name, nationality, date of birth) cannot be changed after submission
- The form must be filled out in English
- You need internet access to complete the application
- High traffic during peak seasons may cause delays in processing
Final Thoughts: Is the TDAC a Game Changer?
Absolutely! The Thailand Digital Arrival Card (TDAC) is a significant step forward in making Thailand’s entry process smoother and more efficient. By digitizing the TM6 form, Thailand is modernizing its immigration procedures, saving travelers valuable time, and improving data accuracy.
However, the conversion from paper to digital might present a challenge for the older generation. My mom for example doesn’t even own a smart phone and won’t be able to complete the online process without help.
If you’re planning a visit soon, be sure to submit your TDAC application before your arrival to enjoy a hassle-free experience at immigration. For more details and to complete your TDAC application, visit: tdac.immigration.go.th.
